About TrailCurrent
Your vehicle should be as smart as everything else in your life. TrailCurrent is the open-source platform making that happen.
Your vehicle's control system hasn't changed in 20 years.
Fixed switches on the wall. Sensors that don't talk to each other. No remote access. No way to check on things from home.
Once you drive off the lot, your vehicle never gets better. The fridge can't be pre-cooled before a trip. You can't tell if a cabinet opened while driving down the highway. You have no idea what's happening with your RV sitting in storage all winter.
Meanwhile, your phone gets smarter every year. Your home thermostat learns your schedule. Your car alerts you when tire pressure drops. But your RV? Your boat? Your UTV? Still stuck in the past.
It doesn't have to be this way.
TrailCurrent makes your vehicle intelligent.
Modular hardware and software that work together to give you real control over your vehicle—from your phone, offline, anywhere.
Control From Your Phone
Turn lights on and off, adjust the thermostat, check battery levels, and monitor sensors—all from an app or web browser on your phone.
Works Offline
No cell service? No problem. The system creates its own WiFi network and works completely independently. Perfect for boondocking and remote areas.
Improves Over Time
Over-the-air updates bring new features and improvements automatically. Your vehicle gets better the longer you own it, not worse.
Modular—Start Small
Begin with a control panel and power module. Add GPS, air quality, battery monitoring, and more whenever you're ready. Each piece just plugs in.
No Subscriptions
Buy the hardware, own it forever. No monthly fees, no cloud subscriptions required. The system is yours.
Why Open Source Matters (For You)
This isn't just a philosophy. Open source gives you real, practical advantages as a vehicle owner.
No Vendor Lock-in
If a company disappears tomorrow, your system still works. Every schematic, every line of code, every design file is published and documented. You're never left stranded.
No Hidden Data Collection
You can see exactly what the software does. Nothing is sent anywhere without your knowledge. Your location, your habits, your data—it all stays under your control.
Community-Driven Improvements
Real vehicle owners contribute features they actually need. Someone who lives in their RV full-time has different priorities than a product manager in an office. That real-world experience shapes the platform.
Build It Yourself
Hardware designs are public. Order your own PCBs from the design files, 3D-print the enclosures, flash the firmware. You have everything you need to build, repair, or modify the system yourself.
Built For Every Vehicle
Starting with recreational vehicles and expanding to anything with a 12V electrical system.
RVs & Motorhomes
Class A, B, C motorhomes and travel trailers. The most complete application with full lighting, climate, power, and sensor support.
Boats & Marine
Marine monitoring, power management, and navigation integration for boats and yachts.
UTVs & Off-Road
Rugged lighting control, GPS tracking, and telemetry for side-by-sides and ATVs.
Motorcycles
Compact modules for touring bikes and adventure motorcycles.
Everything is Open
24 open repositories. Hardware designs, firmware, software, and documentation—all published under the MIT license.
This isn't a product with a closed ecosystem and locked-down software. Every circuit board schematic, every firmware file, every piece of the cloud backend is available for you to inspect, modify, and build on.
Whether you want to buy a ready-made kit or build every piece from scratch, you have everything you need.
View on GitHubBuild It Yourself
Order PCBs from the KiCAD design files, 3D-print enclosures from FreeCAD models, and flash firmware yourself.
Fully Customizable
Modify firmware, create custom integrations, add your own modules. The platform adapts to your vehicle, not the other way around.
Community Driven
Issues, pull requests, and discussions from real vehicle owners shape the roadmap. The features that get built are the ones people actually need.
